Ventilation anchor rod

Abstract

The invention provides a ventilation anchor rod, and belongs to the technical field of construction anchor rods. The ventilation anchor rod comprises a ventilation pipe, an anchor pipe, a baffle ring, an air supply pipe, an air collecting hopper, an adjusting mechanism and an air outlet pipe; the ventilation pipe is used for being inserted and fixed in a side slope, and one end of the ventilation pipe extends out of the side slope; the anchor pipe is located in the ventilation pipe, one end of the anchor pipe extends out of the ventilation pipe and extends in the side slope, and a grouting hole is formed in the extending section of the anchor pipe; the baffle ring is connected with the other end of the ventilation pipe and used for preventing grouting liquid flowing out of the grouting hole from flowing into the ventilation pipe; the air supply pipe is connected with the side slope extending end of the ventilation pipe; the air collecting hopper is communicated and spherically hinged to the air supply pipe and guides natural air into the ventilation pipe through the air supply pipe so as to absorb heat and cool the side slope; the adjusting mechanism is connected with the air collecting hopper and used for controlling the air collecting hopper to rotate in the air coming direction; and the air outlet pipe is used for communication between the interior of the ventilation pipe with the outside so as to exhaust the natural air after heat absorption. The ventilation anchor rod provided by the invention can effectively slow down and even avoid the hot melting collapse phenomenon of the frozen soil side slope.

Description

technical field [0001] The invention belongs to the technical field of construction anchors, and more specifically relates to a ventilation anchor. Background technique [0002] Permafrost refers to all kinds of rocks and soils below zero degrees Celsius. Frozen soil can generally be divided into short-term frozen soil, seasonal frozen soil and permafrost, of which seasonal frozen soil and permafrost can be used for construction. my country is the third largest frozen country in the world. About 98.9% of the country's land area is covered by different types of frozen soil. Among them, the area of ​​permafrost and seasonal frozen soil that has a greater impact on engineering construction accounts for 20% of the total area of ​​the country. 75%. However, with the advancement of science and technology and the development of the times, the environment has been more or less polluted, the climate has become warmer, and some permafrost slopes have thermal melting and slumping, whi...
